Application filed January 21, 1915. Serial No. 8,569.

To all whom it may concern:

Be it known that'I, ROBERT C. Friars,

Jr., a citizen of the United States, residing at Savannah, in the county of .Chatham and State of Georgia, have invented certain new and useful improvements in' Bottle-Closures, of which the following is a specification.

. 'This invention contemplates a new and improved bottle cap especially adapted for use in connection with milk bottles and has as its primary object to provide a device of this character which will form adetachable. closure. for. the bottle'and will also provide a means whereby the contents of the bottle may be readily. poured out.

Theinvention has as a further object to provide a bottle cap composed of but few parts which may be readilydetaehed from each other to permit of cleaning and thus furnish a thoroughly sanitary device and wherein the cap may be readily attached to or detached from any conventional type of And the invention has as a still further object toprovide a bottle cap which will be inexpensive in-construction, thus producing a very desirable article of manufacture.

Uther and incidental objects will appear so las the description proceeds and in the drawings wherein I have illustrated the preferred embodiment of my invention and wherein similar reference characters desig-.

nate corresponding parts throughout the several views, Figure 1 is a sectional View showing my improved cap applied to a milk bottle of conventional form, the bottle being partly broken away, Fig. 2 isa sectional' view showing the'dcap in position within the neck of a bottle, and Fig. 3 is a perspective view'showing the cap detached. Referring more particularly to the drawings, it will be observed that my improved device includes a hollow spout which is substantially rectangular and which, at its inner extremity, is enlarged and terminates in a substantially frusto-conical laterally directed base portion 11, it being observed that the wall of the base gradually increases in width from one side of the base to the opposite side thereof. The outer mar 11 of the wall at the base 11 is bent laterally to provide an annular flange 12 and detachably connected to this flange 12 is a gaslret 13. e

The gasket 13 may be formed of rubber,

cork, or any other suitable material and is substantially channel shaped in cross section, the laterally directed portions of the gasket embracing the flange 12 with the flange seated firmly within the channel of the gasket, it being observed that the gasket 7 is preferably of a width so that the inner.

edge of one of its laterally directed portions will abut the base 11.

While I have indicated that the gasket 13 may be formed of any suitable material, still, rubber is preferably employed so that the laterally directed portions of the gasket will resiliently engage the flange 12 to form a tight joint between the gasket and the said surge.

in Figs. 1 and 2 of the drawings, I have shown my improved device in position within the mouth of a conventional form of milk bottle indicated at '14, the bottle being formed with a neck 15 which as is usual, is provided adjacent its outer extremity with an internal annular shoulder 16, the said shoulder defining an annular seat within the mouth of the bottle disposed to receive the conventional form of pasteboard closure cap;

It will now be observed that the flange 12 is somewhat less in diameter than the diameter of the seat formed in the bottle neck and preferably, the gasket 13 is-of a diameter slightly greater than the diameter of the said seat, so that its outer annular margin will resiliently engage the wall' of the seat.

i As shown in Fig. 1, the spoutlO is remov ably'fitted within the neck of the bottle with the gasket 13 resting upon the shoulder 16, and with the vertical annular wall of the gasket engaging the vertical annular wall of the seat formed by the said shoulder. Since the gasket is preferably of a diameter slightly greater than the diameter of the seat, the spout 10 may be fitted within the seat by imparting a slight turning movement thereto around a vertical axis when the gasket 13 will be compressed to move into the seat formed, in the neck of the bottle. By this arrangement, a tight joint is provided between the spout 10 and the bottle.

Detachably fitting over the outer extremity of the spout, the mouth of which is tionally engage the walls of the spout at the adjacent extremity thereof, for securely holding the cap in position upon the spout.

As Will be noted upon reference to Figs. 1 and 2 of the drawings, the spout 10 is preferably of a length so that the contents of the bottle may be readily emptied through the spout into some suitable vessel, if desired, it being noted that the spout extends laterally and upwardly at a relatively sharp angle from the horizontal plane of the base. I 11, this arrangement of the spout being preferably so that the cap will normally be retained in position thereon.

It will thus be noted that by removing the cap 17, the contents of the bottle it may be readily discharged through the spout 10 while, when the cap is applied, the entire device provides an efiective closure for the bottle. Formed in the Wall of the base ll at the inner extremity of the spout 10 is a vent or opening 18, this vent being provided to facilitate the operation of pouring the contents of the bottle throughthe spout, as will be readily understood.

Particular attention is now proved device, it will be noted as previously set forth, that the gasket 13 may be readily may be easily cleansed While the cap 17 be ing detachable, may also be readily cleaned. In this way, a thoroughly sanitary construction is produced while when the parts are assembled and the device is inserted ithin the neck of a bottle, flies or other insects by no possibility, can gain access to the contents of the bottle. lt is further to beobserved that l eliminate the use of. any hingedly mounted members or other elements so connected to the body of the cap, that the contents of the bottle through being emptied through the device Would'lodge within such connection to not only be exposed to the air and the accessibility of insects, but to also renderv the device unsanitary, as Well as to make the article very difficult to clot-rusew The body of the device including the spout 10, the base ll and the flange 12, it will be observed, is formed integrally and is preferably constructed of some relatively light sheet metal although such as aluminum,

directed to the Y exceedingly simple character of my nn- 7 seatingagainst the detached from the base ll so that it.

Well of the base having an air-vent former: therein upon as-vvill be understood, any other menses cluding a substantially rectangular spout having a substantially frusto conical laterally directed base integrally formed on the inner extremity thereof, the inner margin of said spout being bent to provide a laterally directed annular flange adapted to fit Within the neck of a bottle and being of a diameter less than the diameter of the mouth of the bottle, a substantially channel shaped gaslret having the side portions thereof embracing the said flange with one of said portions base, the said gasket being adapted to yieldably engage within the mouth of the bottle, and a cap detachably fitting over the spout at its outer extremity and having its side vvalls-frictionally engaging the Walls of the spout.

2. In a bottle closure, a body portion eluding an ungulate base having a long side and a short side and provided with a laterallyprojecting annular flange at the larger end thereohthe base at its smaller end having the wall thereof contracted to provide in the body of the de-- an upstanding relatively flat hollow communicating with the base and inclining 1n the direction of he short side thereor, the

the long side of the base .30. immediately contiguous to the juncture the said Wall With the spout, an annul r gasket embracing said flange, and dc tachable cap removably titted over theouter end of the spent.
